Taking the land is obviously their goal, but can Israel accomplish this?
They have yet to secure north Gaza. Hamas is still killing invaders with Yasin RPG and they are still launching bathtub rockets into Israel.
The economic clock is ticking, Israel is taking significant economic damage by having such a huge fraction of their workforce be unavailable. It’s not just the conscripted soldiers, it’s the large civilian population that temporarily fled homes in both the south and north of Israel.
Also the international situation is a wildcard. Without western support, Israel’s only option will be retreat.
